You no longer need to upgrade to version 2 data structures. Newer
releases understand both formats so there's no reason not to upgrade.
Newer releases will down grade any version 2 VG's it finds when you
next *change* the metadata (eg. resize an LV).
Version 2 was bogus and resulted from my not realising that
pv->pe_on_disk.size included all the blank space upto the first PE.
Making pv->pe_start redundant.
